This article focuses on a new concept of quadratic variation for processes taking values in a Banach space B and a corresponding covariation. This is more general than the classical one of Métivier and Pellaumail. Those notions are associated with some subspace ? of the dual of the projective...

В статье анализируется практическое применение теории денежного поля, опубликованной ранее. На основе эконометрического и линейного моделирования временных...

The paper analyzes practical application of money field theory, which was published before. Using econometric and linear modeling of time-series as a basis for the analysis of Canada’s financial indicators, inferences are made towards the country’s stability and actions monetary authorities...

The present paper continues the study of infinite dimensional calculus via regularization, started by C. Di Girolami and the second named author, introducing the notion of weak Dirichlet process in this context. Such a process X, taking values in a Hilbert space H, is the sum of a local...
